5-18. CLEANING PROCEDURES.
Drycleaning solvent P-D-680 is toxic and flammable. Wear protective goggles, face mask, and
gloves and use only in a well-ventilated area. Avoid contact with skin, eyes, and clothes and don't
breathe vapor. Do not use near open flame or excessive heat. The flash point for type I drycleaning
solvent is 100°F (38°C) and for type II is 140°F (60°C). If you become dizzy while using cleaning
solvent, get fresh air immediately and get medical aid. If contact with eyes is made, flush eyes with
water and get medical aid immediately.
DO NOT use diesel fuel, gasoline, or benzene (benzol) for cleaning.
DO NOT SMOKE when using cleaning solvent. NEVER USE IT NEAR AN OPEN FLAME. Be sure
there is a fire extinguisher nearby and use cleaning solvent only in well-ventilated places.
USE CAUTION when using cleaning solvents. Cleaning solvents evaporate quickly and can irritate
exposed skin if solvents contact skin. In cold weather, contact of exposed skin with cleaning
solvents can cause frostbite.
When cleaning ball or roller bearings, place in a basket and suspend in a container of drycleaning solvent, P-
D-680 (item 21, appendix E). If necessary, use a brush (item 2, appendix E) to remove caked grease or chips. Avoid
rotating bearings before solid particles are removed to prevent damaging races and balls.
Do not clean O-rings or other rubber parts in drycleaning solvent. Wipe with a clean, dry, lint-free cloth.
For exterior cleaning of frame and structural components, use detergent (item 11, appendix E) in a solution
as recommended on the container. Leave application on item surface for approximately 10 minutes before rinsing. Rinse
with hot or cold water under pressure. If available, use hot water under 80 to 120 lb (36 to 54 kg) pressure. An ordinary
garden hose may be used if no other equipment is available. If pressurized water supply is not available, wash painted
surfaces with a solution of 1/4 cup soap chips (item 3, appendix E) to one gallon of water.
Electrical parts such as coils, connectors, switches, and insulated wiring, should not be soaked or sprayed
with cleaning solutions. Clean these parts with a clean, dry cloth moistened with drycleaning solvent, P-D-680 (item 21,
